| 摘 要： | 在液相中用马来酸酐接枝高密度聚乙烯(HDPE-g-MAH)表面改性Al(OH)_3以改善其在高分子基相中的分散性。形态观察表明,用适量HDPE-g-MAH处理Al(OH)_3可改善Al(OH)_3在聚丙烯(PP)中的分散性,从而提高体系的力学性能;HDPE-g-MAH用量过多造成的Al(OH)_3粒子间桥联,该现象经熔融混合后依然存在,导致力学性能降低。偏光显微镜观察显示,适量HDPE-g-MAH处理Al(OH)_3可改善PP的结晶形态。

| Abstract: | Aluminium trihydroxide [Al(OH)_3]was modified with maleic anhydride grafting high density polyethylene (HDPE-g-MAH) in liquid phase to improve the dispersion in polymer.The micrographs of PP/Al(OH)_3 showed the dispersion of Al(OH)_3 in PP increased when Al(OH)_3 was modified with HDPE-g-MAH of right content and the mechanical properties of blend improved.The chain linkages between Al(OH)_3 particles caused by bridge effects could be observed under scanning electron microscopic yet after melting blend and resulted in the properties decreased.A better crystalline morphology of PP in blend could be observed under polarizing microscope with Al(OH)_3 was modified with HDPE-g-MAH of right content. |
